Ford F-150 - 1997-2003 :: Rear Air Bags Have Been Deflating When Truck Is Sitting Idle
Mar 11, 2007
I have 97 F250 light duty equipped with factory rear air suspension. Truck has 180K miles. Both rear air bags were replaced about 100K miles ago under warranty (I didnt do it myself!). Both sensors and compressor are new within the last 18 months which I replaced myself. Recently, rear air bags have been deflating when truck is sitting idle. Compressor reinflates air bags as expected when struck is started but recently cannot maintain. Sprayed soapy water today on air bags and airlines and witnessed leak (due to air bubbles) at lower side of air bags on both sides. My conclusion is that air bags are culprit. Seems coincidence that both are leaking??

I am having problems with my 97 F150 6cyl. A couple of months ago, I noticed the truck after sitting for a few days without being started would not crank. After some trial and error, I found that turning the ignition switch on and off several times did the trick and the truck would crank right up. I was thinking this might be a fuel pump or fuel filter issue but, I'm not sure.
A couple of days ago I was going to drive the truck and did the ignition switch deal as usual and the truck cranked up but, there shortly after while just idling the motor died. I have tried and tried to crank it and it want start back. After thinking on it, I don't know if this is a fuel problem or not, or maybe even the ignition box.

I have a 98 F150. The motor was replaced three months ago and have had no problems until now. The truck had trouble starting so i put an alternator on it. Fixed for a while and then it started blowing fuel relay fuses. I replaced fuel pump and filter. Truck has trouble starting after sitting overnight. When I am driving and floor it, once it hits about 4,000 rpms, the truck bucks like its the transmission but the rpms drop and then pick back up. Fuel pressure is right where its supposed to be.

My truck when idling kind of spools up a little bit for a few seconds and then the turbo goes back down. sounds really cool actually. its been doing it since the truck was new, sounds like a plane engine shutting down. It does it over and over sometimes. I just deleted the dpf and unplugged egr last night and now i can really hear it! is this normal....

I've spent several hours over the course of the last week trying to figure out the problem I am having with my 1999 F150. When coming to a stop, there is a heard and felt "clunk" coming from the rear end of my truck. The other day, I had to brake to a stop rapidly and it felt like something had dropped out of the back end of my truck. It's 4WD with a 5.4L V8 with 240k miles. I have a fair amount of knowledge of the truck, having performed all maintenance and most repair, so if I need to check something and report back I should be able to. Also, I've owned the truck since it was new, and this is a recent development.

My truck started to idle very rough. I pulled the codes and I got po308 and po316. First I changed plug #8, the electrode was nearly gone. I have never seen a plug in worse shape. Replaced that plug and fired it up, it still idled rough and threw the same codes. Next I moved the #8 coil pack to the #1 location and vice-versa, still the rough idle and same codes. Then I moved the #8 injector to the #1 location same results. Finally I tested compression in the #8 cylinder and it read 32psi ( not good) everything else read 150 to 160 psi. Squirted some oil into #8 and no difference in compression.The truck is a 2002 with 184,000 miles, it burns a quart of oil every couple weeks but still is in perfect shape. Should I bite the bullet and invest in a remanufactured engine for 2500.00? I put one in my 97 f 150 a few years ago with no problems.

Driving home yesterday I noticed a grinding sound from the driver side rear of the truck. Had a look at the drum brake today and found that the cable to the adjusting lever had snapped and pieces had jammed making the grinding noise. I need to replace the cable and probably have that drum surfaced, but the pads look good.
On the passenger side the hardware is all intact but the shoes look as if they have "spider" cracks everywhere, still lots of shoe left though. What might be causing the cracks on the shoes, and do these need to be replaced? How to do rear drum brakes? (1997 4x4)

So was sitting at an idle in park and truck starts knocking, horrific sound. So shut checked oil, good, went to work came out 8 hours later, started up still knocked. Pulled into drive hit the pedal, knock went away, stopped at red light, knock came back...... Truck has been parked for 3 days, still knocks at an idle but soon as tap the pedal and give fuel it goes away... Tried unplugging injectors one at a time to eliminate, still had knock.

I have a 1998 ford f150 with a 4.6 v8 it has about 170,000 miles on it. The truck seems to run hot when sitting still in park. I have replaced the radiator, the thermostat. I am lost at what could be causing this issue. when I am going the truck will cool down however if you ever let it get hot it takes longer to cool it down as opposed to getting in it and just going and not sitting before going.

I have a 1997 Explorer Sport 4.0 SOHC, 110,000 miles. When I start it in the morning or after sitting for a few hours, the idle is very rough. Most of the time it wont even stay running. My first thought was a vacuum leak. I found four leaks and repaired them, including the EGR valve control and the EGR solenoid. One stem on each was broken off. I bought these parts from the dealer and then tested the vacuum, which I now have vacuum pressure. The check engine light is on and doesnt read the "system evap emission control pressure sensor low" (vacuum leak) anymore, but it now reads "system too lean (bank 1) and system too lean (bank 2). I cleaned the IAC valve and have ran several bottles of injector cleaner through. My mechanic thinks it is the IAC, but when you disconnect the plug on it, the car will barely idle, so it must be working at least a little. I have seen suggestions for a fuel filter, which I am going to replace, but I am really lost here.

ok, its been 9-10 months now, and i have only 3500 miles on my gx.just looked at the back wheel wells.
The left side of the truck in the back is sitting about 1.5 inchs higher than the right rear? I measured the distance between the rims and the edge of the panel in the back. I am baffled. I raised it, lowered it, and still unequal height. Its going to the dealer on wednesday.

My truck is making this chattering when I shift down or just sitting there in neutral it goes away when I press the clutch or if I push the shifter in the spot before the gear I was told it was a throw out baring but I'm not sure I herd this transmission will start to chatter before it goes out so what to do?

I have a 1997 f-150, V-6 absolutely base model, a shade under 80,000 miles. I'm the second owner, and the truck was previously garaged most of the time but now sits out in the driveway. The truck has developed an issue where it will be increasingly hard to start (crank crank crank, intermittent cough) after it sits out in hot weather, which is a problem here in Southern California. When the problem is really bad, it can take all day to get it started (try, wait a bit, try again, etc.). When it does finally catch, it sometimes backfires, idles rough for a few seconds then runs like a champ. I can turn it off and restart it immediately, I can let it sit for an hour or three and restart it, but if it sits out in hot weather it gets increasingly hard to start.
I've scoured various forums, and I've tried every solution I can find. Cycling the key to get fuel in the rail, opening the hood to cool off the engine cavity, trying to start it before it gets hot outside, etc. The truck *is* throwing code p0443, and scouring other forums I think that's either the evap canister purge valve, which my last mechanic replaced, or possibly the charcoal canister, which has not been replaced, but I don't know if that could be contributing (the truck was throwing that code before the hard start developed).

I bought this truck for work and all of a sudden it will rev real high when I press the clutch in to switch gears or when sitting at a light. I stopped at a parking lot and popped the hood and tried to pull the throttle back by hand but it will not go. There is a lil slack in the throttle cable but when the truck is off and I manually pull the throttle back it returns normally.
I was wondering if the little black electronic box opposite where the throttle hooks to the throttle body is making it rev so high? I really don't know a lot about these newer trucks as I have driving older trucks my whole life so probably using wrong terms...

1999 4.6L won't start after sitting a month. Ran fine before, now won't start. Cranks fine. Cannot hear fuel pump turn on when key is turned. Fuel pump fuse is good.
Fuel pump relay clicks a few times when key is turned. Is this normal? I am hoping it is the relay and not the pump. What should I check next? The wires at the pump? What should they read?

It is idling very rough at times, not all the time, when sitting at stop lights/signs. Sometimes it will stall out. 3 times it has stalled in the middle of an intersection while turning. Scary as hell! I Have to stop the van on the side of the road, put it in park, turn it off, then start it again before I can go. This process is getting Old!
While sitting at a stop sign/light, it's like the engine surges up and down. Some surges get low enough that the van will just die. If I step on the gas or put the van in neutral it will quit for a minute. All of the lights in, on, outside of the van go bright/dim with every surge. The battery light will occasionally flash on and off during the surges, but not every time.

2002 Model, F150, 4.6L Triton....
Early last week one day my truck just wouldn't start. I had driven it the day before. but that day nothing. It would spin over just not start. the following day though, it started as always, no hesitation and run smooth. But the was the last day it has ran.
Since then I have checked the relays and fuses. I have checked the inertia switch (pass. side kick panel). Removed the cap on the schrader valve on the fuel rail. (no pressure)
I have sprayed starting fluid into the throttle body and it starts for 1 to 2 seconds. (dies once starting fluid is gone). I have changed the fuel filter and pulled the bed and changed out the fuel pump. I'm thinking about trying the fuel pressure regulator next.
Just not real sure where else to go if that doesn't work.....

I have a buddy that has a 1998 f150 4x4 with 4.6l and 332836 km on it. It will go in to reverse but will not go in to drive at all. Is his transmission shot? Or is there anyway to test it to find out what the problem is.
